Cavity fire barriers - Gyproc Ireland

1 Cavity fire barriers Cavity fire barriers fire separation within concealed spaces Floors and ceilings C06. Cavity fire barriers Cavity fire barriers Regulatory requirements demand that cavities 30 60. and concealed spaces, in the structure or fabric mins of a building, are sub-divided or sealed by means of Cavity barriers or fire -stopping to restrict the hidden spread of smoke and flames. This is of prime importance since many buildings are honeycombed with concealed cavities and voids within the roofs, floors, and walls. Key benefits Cavity barrier performance options to match partition performances up to 60 minutes fire resistance fire separation is maintained throughout Floors and ceilings the life of the building due to the board lining being mechanically fixed High level of component commonality with GypWall partition systems C06.

The fire resistance and sound insulation performances are for imperforate partitions, with all joints taped and filled, or skimmed according to Gyproc 's recommendations. The quoted performances are achieved only if Gyproc and Isover components are used throughout, and the Company's fixing recommendations are strictly observed. Any variation in the specifications should be checked with Gyproc .

Also, due consideration must be given to Important information the class of surface exposed within the Cavity . Fixings through the Cavity barrier framework into the structural soffit must It is also important that smoke and flames are restricted from be capable of supporting the weight of passing from any Cavity in a building element directly into a room or the entire Cavity barrier construction. another Cavity . Therefore, a Cavity must be closed by a Cavity barrier at every junction with another Cavity . Any Cavity contained within Gyproc ceiling solutions are not intended an element is also required to be closed by a Cavity barrier around to provide any support to the Cavity the perimeter of any opening through the element.

Any or, if it abuts against slates, tiles, corrugated sheeting, or other Cavity crossing the edges or ends of a fire resistant element should construction to which it cannot be so fitted, then it must be suitably have a Cavity barrier provided in the same plane as the element, fire -stopped at the junction. Refer to construction details 1 - 2, refer to construction details 3 and 4. There are certain exceptions which show fire -stopping solutions using stone mineral wool.

Cavity barriers must maintain their performance during the life of a building, taking account of any possible building movement due to subsidence, shrinkage, or thermal change. In addition, the possible failure of its fixings or adjacent construction in the event of a fire , and the collapse in a fire of any permitted services penetrating the C06. Cavity barrier, should be considered. ROI: 1800 744480 NI: 0845 3990159 C06.
